Abstract

The mean time to loss of lock and the average switching rate of an automatic frequency control loop operating in fading in the presence of a single interferer are derived. Closed-form expressions and integral form formulas are derived for the general case of modulated carriers as well as important special cases of similar modulations and unmodulated carriers. The general results include, as special cases, some previous more restricted results. Fading channels are assumed to be independent non-identically distributed (i.n.d.) with Rayleigh, Rician and Nakagami-m distributions while the special case of independent identically distributed (i.i.d.) channels is also considered. Corresponding numerical examples are provided and discussed to illustrate the results.
